Phenylthioxophosphane (6) - generated in boiling toluene from endo/exo-10 - reacts under these conditions with hexacarbonylbis(cyclopentadienyl)dimolybdenum (12) to yield the two binuclear molybdenum complexes 13a and 14a.A crystal structural analysis has been performed for 13a.Lawesson's reagent (17) leads under the same conditions with 12 to the analogous complexes 13b and 14b.

The thioxophosphanes RPS (a - f) a), C2H5 (b), C6H5 (c), 4-CH3OC6H4 (d), 4-CH3C6H4 (e), 4-FC6H4 (f)> are stabilized in the protecting coordination sphere of the carbonylmolybdenum and -manganese complexes η2(CO)2RPS>CO (4a - d), 5a, c - f) ( = η5-C5H5Mo(CO) (4), Mn(CO)3 (5)). 4a - d, 5a, c - f are obtained by dehalogenation of the thioxophosphoranes RP(S)Cl2 (1a - d) with Na5-C5H5Mo(CO)3> (2) and activated magnesium in the presence of Mn2(CO)10 (3), respectively, or alternatively with Mg2 in THF.As by-products also the dithioxophosphorane complexes (CO)2RPS2CO (6d, 7c - f) ( = η5-C5H5Mo( CO) (6), Mn(CO)3 (7)) are formed by sulfur transfer reactions.For the generation of 4, 6 electronic reasons are relevant.Considering the formation of the manganese compounds 5, 7 a distinct dependence of the product distribution is observed on the steric demand of the organic substituents R. 6d crystallizes in the triclinic space group P1/ with Z = 2.

Lawesson's reagent (the dimer of (p-methoxyphenyl)thionophosphine sulfide) reacts with dicyclopentadienyltetracarbonyldimolybdenum or -ditungsten to give binuclear complexes containing a phosphinothioylidene ligand. These complexes were characterized on the basis of analytical and spectral data and a single-crystal X-ray analysis of the molybdenum complex. Crystal data of [(C5H5)2Mo2(CO) 4(SP-C6H4OCH3)] are as follows: a = 9.471 (4) ?, b = 9.119 (3) ?, c = 16.145 (2) ?, α = 90.75 (2)°, β = 97.37 (2)°, γ = 126.89 (3)°, V = 1098.8 ?,3 Z = 2, triclinic, space group P1. Intensity data were collected by counter methods, Mo Kα1 radiation. The structure was refined on 3541 reflections with I > 2.30σ(I) to RF = 0.020 and RwF = 0.028. The P atom is σ bonded to Mo(1) and P=S π bonded to Mo(2): Mo-Mo = 3.245 (1) ?, Mo(1)-P = 2.326 (1) ?, Mo(2)-P = 2.451 (1) ?, Mo(2)-S = 2.567(1) ?, P=S = 2.022 (1) ?, Mo(1)-P-Mo(2) = 85.53 (3)°. One carbonyl attached to Mo(2) is semibridging: Mo(2)-C(21) = 1.968 (3) ?, Mo(1)?C(21) = 2.864 (3) ?, Mo(2)-C(21)-O(21) = 166.0 (2)°.
